Abstract

PROBLEM TO BE SOLVED: To rotate a vessel stopped in an inspection station without losing control. SOLUTION: This inspection machine has a support carrying track 12 of a bottle 10 and a car means to carry the bottle 10 along the bottle support carrying track 12 to an inspection station, and inspects the glass bottle 10. The car means has a roller to rotatably engage with one side surface of the bottle 10, and a wall mechanism forcedly engages with the other side surface of the bottle 10 when the bottle 10 is carried to the inspection station. The wall mechanism has a turnable support part 24, and the support part 24 is energized toward its completely advanced position. A straight line-shaped bumper 22 fixed to the support part 24 extends in a track of the carrying bottle 10 when the support part 24 exists in the completely advanced position, and as a result, the bottle 10 engages with the straight line-shaped bumper 22, and the support part is forcedly turned and moved to a retreat position when it is carried to the inspection station.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a machine for inspecting glass containers. More specifically, the present invention relates to a machine for stopping a conveyed container and performing inspection while rotating the container at an inspection station.

[0002]

BACKGROUND OF THE INVENTION In order to maintain a constant speed in the manufacturing process, it is necessary to inspect at least 400 containers per minute. At such an inspection speed, stability of the container is important, but this is a serious problem when rotation of the container is required at the inspection position.

[0003] In the conventional design of rotating and inspecting containers at an inspection station, multiple containers can be propelled from the inspection station, but this is not desirable.

[0004]

SUMMARY OF THE INVENTION One object of the present invention is to provide an inspection machine that can rotate a stopped container at an inspection station without losing control.

[0005] Other objects and advantages of the present invention are:
BRIEF DESCRIPTION OF THE DRAWINGS The following description of the present specification, which illustrates the presently preferred embodiments, embodying the principles of the present invention, will be apparent from the accompanying drawings.

[0006]

In order to achieve the above object, the present invention provides a machine for inspecting a glass container, comprising: a supporting and conveying path of the container; and roller means for rollingly engaging one side of the container. A car means for transporting the container to the inspection station along the transport trajectory; and a movable support for engaging the other side of the container when the container is transported to the inspection station. A wall mechanism, biasing means for biasing the movable support toward its fully advanced position, and linear bumper means mounted on the movable support; When the movable support is in the fully advanced position, the linear bumper means extends into the transport path of the container, so that the container engages the linear bumper and is transported to the inspection station. When The movable support is forcibly moved to the retracted position, and the length of the linear bumper means is such that when the container is transported to the inspection station, the container passes through the linear bumper means, The movable support is selected to return to the fully advanced position, and the machine is further mounted on the movable support and the movable support is fully advanced When moved into position, forcibly engage the other side upstream of the container at the inspection station;
Roller means, an idler roller engaging the other side downstream of the container located at the inspection station, and supporting the idler roller to move the idler roller to the container by further transporting the container from the inspection station. Means for driving the roller means to rotate the container located between the roller of the car, the idler roller and the roller means of the movable support, and the inspection station. And a means for inspecting the container rotating in the step (a).

[0007]

DETAILED DESCRIPTION OF THE INVENTION A plurality of bins 10 are conveyed by a conveyor 12 which defines a bin path or track (supporting and conveying path for glass bottles). A car means 14 that is part of a drive chain (not shown) and runs at the same speed as the conveyor 12 when the bin approaches the inspection station.
(FIGS. 2 to 4) show a pair of rollers 18 which are vertically separated from each other.
Capture the bottle during. At this time, the bin is located between the spaced roller pair 18 on one side and the wall 20 on the other side (FIG. 2).

When the bin approaches the inspection station (FIG. 3), the upper and lower linear bumpers 22 are made of plastic strips (in FIG. 2, the upper linear bumper is shown to indicate the lower linear bumper). Partially cut-out) extend into the transport path of the bin. Each linear bumper is fixed to the support 24. The supporting portion is fixed to the bracket 27 by screws 26 with the spacer 25 interposed therebetween as appropriate. The bracket is fixed to a spindle shaft 28 and is typically pivoted by an air cylinder 30 extending between the bracket 27 and the housing 32 to move the linear bumper 22 to its fully advanced position.

Here, the wall 20 and the support portion 24 fixed to the bracket 27 and supporting the linear bumper 22 constitute a wall mechanism that engages with the other side surface of the bin.
The air cylinder 30 constitutes means for urging the support portion 24 (the linear bumper 22) to its fully advanced position via the bracket 27.

Further movement of the bin causes the bracket to pivot gradually about spindle shaft 28 to the fully retracted position shown in FIG. When the bin arrives at the inspection station (FIG. 4), it passes through the straight bumper, thereby allowing the straight bumper to be biased by the air cylinder toward a fully advanced position. When this occurs, the support 24 of the linear bumper
A pair of vertically spaced roller means 34 fixed to a drive shaft 36 supported by the forcibly engage the bin (the pair of vertically spaced roller means 34
When the bin is at the inspection station, it is forced into engagement with the other side of the bin, the upstream side, which is the right side of FIG. 4, as shown in FIG. 4). As shown in FIG. 5, the vertically spaced roller means 34 is preferably a nested roller, whereby the roller means can be adjusted above and below the drive shaft 36. .

The drive shaft 36 is driven by a drive pulley device 38 interconnecting the drive shaft 36 and the spindle shaft 28. The motor pulley device 40 interconnects the spindle of the continuously operating motor 42 with the spindle shaft 28 supported by a block 44 fixed to the housing 32. Here, the continuous operation motor 42 rotates the bin located on the inspection station by driving the roller means 34 via the motor pulley device 40, the spindle shaft 28, the drive pulley device 38 and the drive shaft 36.
Supported by a pivotally mounted arm 52,
The pair of idler rollers 50 is biased by a spring 54 to forcibly engage the bin at the inspection position (FIG. 4).
, Forcibly engaging the other side of the bin, the downstream side, which is the left side of FIG. 4). At the time of inspection,
With the rollers 18, idler roller 50 and roller means 34 of the car means 14 engaged with the bin 10, as shown in FIG. 4, the bin is rotated on the inspection station. When the inspection is completed, the continuously moving car means pivots and passes the bin on the idler roller which is off the transport track. Here, the arm 52 pivots the idler roller out of the transport path of the bin when the car means passes the bin over the idler roller.

As can be seen from FIG. 2, the vision device having the camera 56 observes the bin at the inspection station between the vertically spaced drive roller means 34 and the idler roller 50, whereby the bin is observed. Are inspected. The bin is backlit by a light source 58 as appropriate.
